"On December 18 I'm going to make history by adding another world title to my collection," said Barthelemy. "Shafikov is a very tough opponent and at this level everyone is dangerous. I'm taking this fight very seriously and the boxing world will take notice of my presence in the ring. Fans love to see action and that's what I bring to every fight. I'm going to send a stern message to the world of boxing that I'm one of the best in the sport."

"I've been preparing my whole life for this fight and to become a world champion," said Shafikov. "This is my second world title fight and while I have a great deal of respect for Barthelemy, I will be victorious on December 18. My trainer Abel Sanchez and I have been working hard for the past couple of months and we will have a great game plan on fight night."

"I am happy to get back in the ring again because I want to fight all of the best fighters in the cruiserweight division," said Shumenov. "I would like to stay more active because I'm still developing. I am curious to see my progression and how I will do against the best cruiserweights."

"I'm very excited to be fighting a well-known opponent in Las Vegas," said Wlodarczyk. "Shumenov is a tricky guy, but he has no heart. He tried to run from the action in his last fight. I do not like to fight guys who run but if I want to fight the best I have to destroy this chicken and I will do it."
